Characteristics of Ground Pressure Disaster and Rockburst Proneness in Deep Gold Mine

چکیده
Abstract To obtain rockburst characteristics at rock engineering, the event, in situ stress characteristics, and proneness are studied a deep gold mine. The severity of increases with cover depth main locations spalling events include roof sidewall. measurement results show this area that is controlled by horizontal constructional pressure, self-weight also has an important influence. mechanism analyzed from principal tangential stress. When maximum (MTS) does not exceed 0.4 times UCS surrounding rock, no obvious disaster tunnel found. MTS between about ~ 0.55 may suffer spalling. exceeds serious failure occur tunnel, such as large collapse. relatively hard complete (high impact energy index, elastic strain linear RQD index), plays very role

Pyhäsalmi mine in central Finland provides an excellent opportunity to study microbial and geochemical processes in a deep subsurface crystalline rock environment through near-vertical drill holes that reach to a depth of more than two kilometers below the surface. However, microbial sampling was challenging in this high-pressure environment. Nucleic acid yields obtained were extremely low when...

In order to strengthen the prediction of rockburst and inquire the relationship between the rockburst proneness of rock and its surface fractal characteristic, the surface fractal of the rock was studied by fractal method and uniaxial compression test. The change rules of surface fractal of different types of rock were compared by calculating its fractal dimension of rock before experiment and ...
